NM, figured it out. Your distance is unlimited, so you can actually go all the way to the little square at the bottom right, then teleport even lower into the new rooms. Yeesh, that wasn't obvious! Heh.

I loved that game. Obvious Portal hommage, but that's of course perfectly fine. It managed to capture the gameplay quite well, but the voice is nowhere near as authentic and enjoyable as Glados from Portal.

OK, decided to give the game a second chance. Made it to level 12, now I'm stuck at the first challenge. I can see I need to crush the beacon with the spike box, but can't figure out how to get the spike box to the beacon.
